Funny lines - not interlace lines.

I don't have the original sources with me but all I did was IVTC the thing and I saw some scenes which had these colorations.

This was encoded with 5.02. Is it my fault or the DVD's?

It looks like you've used mpeg2dec3 to pass YV12 directly to DivX. The DVD is chroma sampled as interlaced but DivX uses progressive upsampling for display, resulting in the artifacts.

Maybe you used Decomb with postprocessing disabled and these scene change frames came through combed. If you get rid of all the combing you'll get rid of the artifacts.

As Sirber requested, post your complete script file so we can determine the source of your problem and what you can do about it.

I sorry to say that I can't reproduce the log file.

Well, what happened is that I encoded the movie over a month ago, and then decided to watch it again. Usually when I finish encoding, I check for audio synch, visual quality, etc. but I guess I missed those parts in the pictures that I posted. Btw, wouldn't the avs file tell you more than the log file?

Maybe I'm not too familiar with the forensics of video encoding.

All I can tell you is that I did not use avisynth 2.5, but rather the old 2.06 before the use of YV12. I use GKnot and frameserve to VDub, so my avs file consists of:

decomblegacy.dll (ver. 4.0), mpeg2dec.dll, neutral bicubic resizing (0.5 value, I believe), cropping and resizing (with even values, divisible by 4), IVTC and my source files. No filters were applied.

I'm not sure if any of this helps but thanks for reading.

I ask for the script and you reply by asking wouldn't the script file tell me more.

Without a script and unprocessed VOB fragment, I can't help you.
